PIROCESS OF DECQEATING V0013.

Application filed August 2, 1915.

To all whom it may] concern:

Be it known that T, PAUL Scrnzmrtr, a citizen of United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Processes of Decorating l/Vood, of which the following is a specification.

The present invention relates to the production, by an economical method, of wooden panels, or other wooden articles, resembling inlaid work of another color.

In carrying out my process, I first obtain a board of any desired thickness, preferably of a light colored wood. This board, or one surface thereof, may then be treated by planing, sand-papering, rubbing down with pumice or any other suitable method of obtaining a smooth finish. The wood thus treated may if desired be treated with any desired conditioning agents, such as bleaching agents, varnishes, oils, polishes, dyes or the like, although this step is optional.

Upon the surface of the wooc thus obtained, I print, by any suitable method, lines representing any desired ornamental figures, flowers or the like, said lines representing closed figures.

The wooden surface is then treated inside the lines representing the closed figures, with a solution of dextrin, and the surface outside the lines being coated with shellac. Both these are preferably applied by means of a brush, the strength of both solutions depending upon the temperature of the room, the amount of moisture in the atmosphere, etc. The cooler the room, and the more moisture present in the atmosphere, the stronger will be these solutions.

T then run a roller, coated with a suitable paint, a roller like a printers roller being suitable, over the entire surface of the wood. The paint adheres to the wood where shellac has been applied but not where the dextrin has been applied.

The paint used should preferably be an oil paint, a turpentine paint, or an oil stain, but should not be a water paint (distemper paint) and may be of any desired color, for example black walnut, dark oak, mahogany or the like, and is in any event of a darker color than the wood to which it is applied. Thus for example the original wood beingmaple, yellow oak, red oak, yellow pine, white pine, bass-wood or the like, I may apply to the printed and treated wood,

Specification. of Letters Patent.

Serial No. 43,307.

a dark oak or mahogany stain, which is preferably an oil stain. After drying, the entire surface may be varnished or treated. with any desired transparent finish, to protect the work.

The result is an article which very closely resembles dark colored wood, having light colored wood inlaid therein, and my process produces this at a cost which represents a very small fraction only, of the cost of such inlaid work.

While I have particularly referred to special kinds of wood, I will state that any suitable wood may be employed in the process.

I am, of course, familiar with the fact that material such as paper has frequently been printed, successively with various colors, and I particularly state that I do not desire to claim the treatment of materials other than wood, in accordance with this process. While the lines, representing the pattern may be printed with any desired kind of ink, ordinary black printers ink appears to give good results.

The ground work may be applied by means of a brush in the ordinary manner, but it is preferably applied by means of a roller, and in printing this on, any suitable graining effects may be produced, in the well known manner.

The accompanying drawings illustrate the invention. In said drawings, Figure 1 shows a plan view of a piece of wood treated in accordance with the invention and Fig. 2 shows on an exaggerated scale, a section of such an article.

In such drawings, the numeral 1 indicates parts of the surface upon which the lines are printed, the ink being somewhat absorbed by the wood. 2 represents portions of the wood within such lines, to which the dextrin is applied. 3 represents portions of the wood which have absorbed the stain, and 4 represents a layer of varnish applied over the entire surface, after washing off the water-soluble resist.

What ll claim is 1. A process of imitating inlaid wood which comprises (a) printing designs upon the wooden article, said designs representing closed figures, (b) treating inside of the outline of said figures with a water-soluble repellent resist; (a) treating outside of said line with a material to which paint will adhere, (cl) passing a paint roller over the entire surface, whereby, the portion of the surface outside the said lines becomes coated with the paint, (0) and drying the painted surface.

2. In the described process of producing imitation inlaid WOOCl Which comprises (1st) producing an entirely smooth surface to the Wooden article, (2nd) bleaching said surface, (3rd) printing upon the smooth bleached surface an outline representing the outer edges of the inlay, (4th) treating the surfaces inside of said outlines With deXtrin, and treating the surface outside said outline with shellac, (5th) passing a paint roller over the entire surface, whereby the paint adheres to the portlon of the Wood treated with shellac and not to the portion treated with dextrin, (6th) drying the painted surface and (7th) varnishing the entire surface. In testimony whereof I afiix my signature in presence of two Witnesses.
